METHOD OF MAKING CONTAINERS.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed June 10, 1914. Serial No. 844,307.

To all Whom it may concern:

Be it. known that I, CARL KomrANsnAUs, a subject of the Emperor of Germany, residing at Barmcn, Germany, have invented new and useful Improvements in Methods of Making Containers, of which the following is a specification.

This invention relates to the manufacture of containers or boxes, such as used for holding commodities. It is important that the appearance of these boxes should be neat and attractive, as the sale of the goods which they carry depends largely upon this. For this reason such boxes are usually provided with a covering or facing sheet of glazed paper, or otherwise ornamented paper. Such boxes usually comprise a neck which extends upwardly and forms a seat for the lid. It is difficult to cover a neck box of this kind by machinery.

One of the objects of this invention is to provide an improved method for forming boxes, which will enable the boxes to be covered by machinery.

A further object of the invention is to provide a method which will enable contrasting colors or different designs to be used in covering the box, so as to improve the neatness and attractive appearance of the finished box.

A further object. of the invention is to produce a method for forming a hinged lid box, whichis very simple in practical operation. I

In the drawing, which fully illustrates the manner in which my method is applied to the construction of boxes, Figure 1 is a perspectii'e of a bottom box shell, which I form in carrying out the invention. Fig. 2 is a perspective of the lid box shell which I form. Fig. 3 is a transverse vertical section through the box at a more advanced stage in its manufacture, and particularly illustrating the step of producing the movable lid. Fig. 4 is a vertical section through the completed box, having the usual removable lid. Fig. 5 is a vertical section taken at the back of a box of hinged lid form. and showing the lid partially raised. Fig. 6 is a perspective showing'this form of the finished box with lid partly raised.

Fig. 7 illustrates the form of the blank from which the parts of the box are most conveniently formed.

In carrying out my invention I prefer to form a bottom box shell 10, and a lid box shell 11, the former of which carries the bottom 12 of the box from which side walls 13 extend upwardly. The lid shell 11 is similar to the shell 10, and is simply an inverted box shell of slightly larger size comprising a lid wall 14 and vertical side walls 15. After forming two box shells 10 and 11 in this way I cover them by machinery, that is I place on the lid section a covering 16, which completely covers its lid wall and side walls, and has its edges 17 secured under the lower edges of the side walls 15. I place a similar covering 18 on the bottom shell, which covers the bottom of its under side, and which extends up on the outer side of the side walls 13, and over the upper edges of the same. If desired this covering 18 may be extended down into the interior of the box so. as to form a lining therefor. Having covered the box shells as described I telescope them together in the manner in dicated in Fig. 3, preferably with a block 19 of wood or similar material on the interior. In applying the two box shells together I prefer to attach the side Walls of the sections together at their lower portions as indicated at 20, preferably with an adhesive. According to my invention the box may be of the usual removable lid type, or it may be of the hinge-lid type. In both boxes the lid is made relatively movable.

In forming a hinge lid box such as that illustrated in Fig. 6, I divide the vertical Wall of the outer shell on three sides. This may be accomplished by means of a rest 21, which supports the box and inclosed block in substantially horizontal position, said rest supporting the circular knife or cutter 22 past which the box may be shoved while belng pressed against the knife. The rest presents a vertical guide wall 23 which prevents the cutter from cutting into the inner wall 13 of the box.

If the lid shell is formed from a blank, which is a matter of convenience, the point on the blank which will form the rear wall 15, is provided with a score line so that when the completed box is formed a weakne'ss occurs at this point indicated at 24, in Fig. 3, and this point 24 is located so that it will be at an intermediate point on the height of the wall on a line with the position of the knife so that it lies opposite to the dividing line or incision formed by the knife. After the box has been cut on three sides, as described, the lid can be raised, the point it acting as a hinge line as seen in Fig. 5. The block 1.) is then removed. and the box is ready to receive anything which it is to contain. Forming a narrow cut or incision in this way produces abutting edges on the lid shell, and the part below these abutting edges becomes virtually a part of the bottom shell. These abutting edges formed by the incision support the lid at all points around the box. This support at all points is particularly desirable where the box is not a neck box, because in the absence of a neck, the lid must be supported by the outer shell. By cutting through the outer wall on all four sides a box of the type shown in Fig. 4 is formed in which the lid can be removed entirely from the box.

The shells may be conveniently formed from blanks of the form illustrated in Fig. 1, each blank comprising a body-portion and [laps 26 and 27, which fold upon the body portion to form the side and end walls of the box. The llap .28, which is toform the back wall of the box, it the box is to he a hinge lid box, is provided with a score line 29, which in the finished box, forms the hinge line 24. \Vith a box constructed in this way it will be seen that a dilterent kind of paper may be employed for covering the bottom shell from that which is employed for the lid shell, and in this way contrasting colors may be employed, giving the box a striking ornamental appearance, and other ornamental effects may be brought about.

I may construct the box of the type shown in Fig. 5 without covering the telescoping sections before they are telcscoped.

It is understood that the embodiment of the invention described above is only one of the forms or embodiments the invention may take, and I do not wish to be limited in the practice of the invention, nor in my claims, to the particular embodiment set forth.

hat I claim is:-

1. The method of making a box which consists in forming a blank with a flap to make a rcarwall, forming a score line in said [lap at an intermediate point thereupon, forming a box lid shell including the lid wall from said blank. forming a box bottom shell including the bottom wall of the box, telescoping said shells together, attaching the lower portions of said shells together below said score line in the rear wall and cutting the outer shell on a single continuous line lying wholly in the plane of said score line to form the outer shell wall into two parts having abutting edges which abut when the box is closed. said score line i'ornr ing a hinge line for opening the lid.

:2. The method of making a box which consists in forming a blank with a flap to make a rear wall, forming a score line in said fiap at an intermediate point thereupon. forming a box lid shell including the lid wall from said blank, forming a box bottom shell including the bottom wall, telescoping said shells together, attaching the lower portions ot said shells together below said score line in the rear wall and cutting completely through the outer shell on the torwarddvall and end walls in a continuous line lying. wholly in the plane of said score line and thereby dividing the'outer shell wall into two parts only, having abutting edges between the upper part of the lid shell and the lower portion of the box which abut when the box is closed, said score line forming a hinge line for opening the lid.

In testimony whereof I have hereunto set. my hand in presence of two subscribing witnesses.
